Musical Mixes of Classical India and The West: Exploring Novel Styles

Indian music has a rich history, beginning in ancient times with the Aryans who used music as a religious practice. It continued developing through the centuries growing and expanding into a system that has its own unique theory, notation, instrumentation, and vocal style. One of the most dynamic periods in the history of Indian music was during colonization when, as early as the fifteenth century, India was introduced to Western cultures. Even though the cultures refused to mingle at first, an appreciation between them eventually developed, leading to an interesting exchange. Slowly but surely, through the pressures of Western ideals and the introduction to Western musical styles, a hybrid style gradually formed. This progression toward the new blend can be observed through the centuries by examining the genre of Hindustani Airs and the composer Mutthuswami Dikshita during the eighteenth century, through the compositions of Rabindranath Tagore (1861-­‐ 1941) in the nineteenth century, and through the life of the composer and sitar player Ravi Shankar (1920-­‐2012) in the twentieth century. The earlier novel styles, propagated by the British, portray India as a British colony where as later novel styles establish India as an independent country with its own musical sound

Voltage control in a distribution system using active power loads

High penetration of renewable energy resources such as rooftop solar photovoltaic (PV) systems is exacerbating violations of the voltage limits in power distribution networks. Existing solutions to these over-/under-voltage issues include tap-changing transformers and shunt capacitors. However, tap changers only allow voltage changes in discrete steps and shunt capacitors cannot handle over-voltage situations. To overcome these problems, this thesis proposes voltage control in a distribution system by adjusting active power loads. The proposed solution can be used for both under- and over-voltage cases at any levels of voltage adjustment. First, the active power that needs to be adjusted at selected nodes to bring the voltages within acceptable limits is calculated for under and over-voltage cases using alternating current optimal power flow (ACOPF). ACOPF is solved for three different cases by varying the cost of active power adjustment and the marginal cost from the feeder supply, which is assumed to be the market price. Secondly, demand response on electric water heaters is implemented to achieve active power adjustments at selected nodes obtained from the ACOPF results. The problem is formulated over multiple time steps to minimize the energy costs of water heaters at a specific node subject to the dynamics of the water temperature, the energy consumption, the temperature constraints, and the voltage limits at the node. The IEEE 34-bus radial distribution system is used as a case study. By solving the same problem for different price settings, it is observed that the price structure affects the energy demand only in the under-voltage system, but not in the over-voltage system. The main contribution of this thesis is to show that by adjusting active power loads, voltages in a distribution system can be maintained within the permissible limits --Abstract, page iii

Overcoming Forensic Implications with Enhancing Security in iOS

As the decades passed, smartphones have come to their greatest inventions. But their history has more than 2500 years starting from a basic thing of strings and beads, i.e. from the Abacus to the latest of our present iPhone. With every special invention in this area brought people together socially over the internet. This, in turn, raised the alarm for having secured communication. With these devices getting popular, development in the technology to enhance the security features in those devices has also been increasing. These advancements have brought Apple operating system (IOS) into light. These devices are one step ahead of all other smartphones regarding storage by having space for storing emails, GPS data and many more. This feature of storage has a major advantage in conducting forensics for investigation purposes. In this research, I performed data acquisition on iPhones with two different OS versions using various forensic tools and then compare the forensic implications with variant security features. I analyzed the forensic implications with enhancements in security and iPhone operating systems over the years. I also used to software to break the iPhone passcode which is the major forensic implication caused

Monitoring the low doping regime in graphene using Raman 2D peak-splits: Comparison of gated Raman and transport measurements

Avoiding charge density fluctuations and impurities in graphene is vital for high-quality graphene-based devices. Traditional characterization methods require device fabrication and electrical transport measurements, which are labor-intensive and time-consuming. Existing optical methods using Raman spectroscopy only work for doping levels higher than ~10^12 cm^-2. Here, we propose an optical method using Raman 2D peak-splitting (split between the Raman 2D1 and 2D2 peaks at low doping levels). Electrostatically gated Raman measurements combined with transport measurements were used to correlate the 2D peak-split with the charge density on graphene with high precision (2x10^10 cm^-2 per 2D peak-split wavenumber). We found that the Raman 2D peak-split has a strong correlation with the charge density at low doping levels, and that a lower charge density results in a larger 2D peak-split. Our work provides a simple and non-invasive optical method to quantify the doping level of graphene from 10^10 cm^-2 to 10^12 cm^-2, two orders of magnitude higher precision than previously reported optical methods. This method provides a platform for estimating the doping level and quality of graphene before fabricating graphene deviceshttps://arxiv.org/abs/1908.10961First author draf

Mars Atmospheric and Climatic Survey System

Before Mars can be explored by humans, its extreme climate and environment must be investigated. This can be achieved through the deployment of weather station probes capable of measuring Martian air temperature, atmospheric pressure, relative humidity, and wind speed. The Mars Atmospheric and Climatic Survey System (MACSS) aims to collect this data, allowing predictive models of global climate patterns on Mars to be developed. These models will aid NASA in providing the needed knowledge to prepare for long-term exposure to the conditions on Mars. The probes are compact and lightweight; they have been designed to withstand Mars’ harsh environment: extreme temperatures, statically-charged dust particles, a thin atmosphere, and intense solar radiation. Considerations of deployment were also made, with the size and weight of each probe allowing for them to be deployed as-needed and as accessories in future missions rather than simultaneously in a single mission. With regards to components, solar panels are to supply the probes with primary power. Data would be collected by sensors and stored on a solid-state drive. A low-gain antenna would establish communication between the probes, NASA’s Deep Space Network, and Mars’ rovers and orbiters. This data can then be evaluated on Earth, allowing models of Martian climate to be formed. In order to demonstrate the feasibility of MACSS, a mockup was designed, simulating data collection in real time with Earth-equivalent components. With continued collaboration, MACSS and its probes can be further optimized for deployment to and longevity on Mars.https://scholarscompass.vcu.edu/capstone/1202/thumbnail.jp

Preparation Of Control And Region Well-Organized Near Multipliers

Proximate computer can control design hardness increasing performance and energy efficiency of error-instantaneous typing This short covers the new manufacturing process of estimating quantity. Incomplete quantity products are modified to bring about a changing environment. The reasonable rigidity of the assumptions varies in the collection of selected materials depending on their capabilities. Specified hypotheses are used in two different types of 16-bit multipliers. The results of that synthesis show that both of these components increase energy efficiency by 73% and 39%, respectively, compared to the actual mass. They have better accuracy compared to the current approx quantity. The performance of the enhanced frequency is assessed through the use of image processing, with one of the types designed to achieve a high signal-to-noise level

CARBAMAZEPINE INDUCED HYPERSENSITIVITY SYNDROME- A CASE REPORT

Anti-convulsant drugs elicited hypersensitivity syndrome could be a rare side effect of the primary line anticonvulsive medication like carbamazepine and alternative aromatic agents. We here mention a rare case of gastrointestinal and skin findings associated with carbamazepine administration that is incredibly uncommon and desires to be reportable.We report a study done on a 22-year woman with carbamazepine associated hypersensitivity syndrome, who developed diarrhea, fever and skin lesions. On withdrawal of carbamazepine and administration of methylprednisolone in the patient, all initial skin related symptoms, GIT symptoms were relieved and white blood corpuscle count normalized. Anticonvulsive drug hypersensitivity syndromes can present with a wide spectrum of unspecific symptoms, which the prescribing clinician should be aware of
